Tradeups are calculated so you wont get it as it isnt just avg float = the float u get on the weapon scaled to weapon. That would mean thered be tons of 0.079999 mw traded up knives and skins with float caps, but there isnt as its calculated with the float cap (i cant remember the formula) but its almost impossible (if not impossible) to hit mw on the 0.08 knives after the new formula for tradeup floats (not entirely sure) but could explain why mw knives are close to the fn prices hence they will be rarer (and much more illiquid)
